Square API Overview: The Square API is a set of RESTful APIs that allow developers to integrate Square's payment processing and other services into their own applications. The API is well-documented and provides a wide range of functionality, including the ability to create and manage customers, process payments, and manage inventory. Square also offers webhooks, which allow developers to receive real-time notifications about events that occur in their Square account. The API is subject to rate limits, which are designed to prevent abuse and ensure the stability of the platform. Developers should familiarize themselves with the API documentation and rate limits before using the API.
